In the past when fire walls were an issue, we would usually build a stud wall on one side of the fire wall so we wouldn't have to worry running anything through the firewall. But, that might be out of your scope of work.
Your mini closet idea sounds pretty good, except you would have the penetrations through the drywall for your conduit.
You could use a 3M or Hilti putty or firecaulk that has the same hourly rating as the wall.
You may want to talk with the owner to see if they're okay with the mini closet idea and cost, then take it to the AHJ.
I can't remember what number(s) they are, but there are also UL listing for penetration ratings. If there is a project Architect / Engineer you may want to ask what his spec for penetration fire rating is.
As far as sound separation, you could use a layer of sound board under the drywall on one side, or over the the rated drywall with a layer of drywall over that.
I hope this helps.:smile:
